Abstract
Abstract An apparatus for providing dripless consumption of a consumable liquid includes a preferably concave saucer and a container having a liquid-receiving body with a flange provided at its bottom. The flange has a series of indentations formed therein that act to retain liquid during the drinking sequence, and prevent liquid found on the exterior of the container from dripping onto the user.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
133 words
An apparatus having a drip prevention feature, and comprising: a saucer having an upstanding lip defining a container-receiving area thereon in which liquid may collect; and a container having a liquid-receiving body, said body being provided at its bottom with a flange adapted to fit on said container-receiving area of said saucer, said flange having a series of indentations formed therein, said indentations being spaced from one another so as to form a series of substantially flat areas about the bottom of said flange between said indentations, said flat areas between said indentations being substantially in the shape of a trapezoid, said indentations being formed so that liquid adhering to said flange when said container is removed from said saucer is retained within said indentations and thereby prevented from dripping from said container.
Claim 2
Independent Claim
133 words
An apparatus having a drip prevention feature, and comprising: a saucer having an upstanding lip defining a container-receiving area thereon in which liquid may collect; and a container having a liquid-receiving body, said body being provided at its bottom with a flange adapted to fit on said container-receiving area of said saucer, said flange having a series of indentations formed therein, said indentations being spaced from one another so as to form a series of substantially flat areas about the bottom of said flange between said indentations, said flat areas between said indentations being substantially in the shape of a trapezoid, said indentations being formed so that liquid adhering to said flange when said container is removed from said saucer is retained within said indentations and thereby prevented from dripping from said container.
Claim 3
Dependent Claim
36 words
The apparatus of claim 1, wherein said areas on the side of said flange between said indentations shed liquid present within said container-receiving area of said saucer when said container is lifted upwardly off said saucer.
Claim 4
Dependent Claim
34 words
The apparatus of claim 1, wherein said indentations extend above the top of said upstanding lip of said saucer when said bottom of said container is placed within said container-receiving area of said saucer.
Claim 5
Dependent Claim
24 words
The apparatus of claim 1, wherein said flange is substantially circular, and wherein said indentations are spaced about the circumference of said circular flange.
Claim 6
Dependent Claim
12 words
The apparatus of claim 4, wherein said indentations are arcuate in cross-section.
Claim 7
Dependent Claim
25 words
The apparatus of claim 5, wherein the topmost point of the arc of said indentations extends above the top of said lip of said saucer.
Claim 8
Dependent Claim
13 words
The apparatus of claim 4, wherein said indentations are 1/4 inch in width.
Claim 9
Dependent Claim
32 words
The apparatus of claim 4, wherein the outer edges of said substantially flat trapezoidal areas on the bottom of said flange between said indentations have an outer dimension of approximately 1/16 inch.
Claim 10
Independent Claim
197 words
An apparatus for providing dripless consumption of a liquid and comprising: a saucer presenting a concave surface, said concave surface having an upstanding circular lip defining an enclosed container-receiving area thereon in which liquid may collect; and a container having a liquid-receiving body, said body being provided at its bottom with a circular flange adapted to fit within said container-receiving area of said saucer, said circular flange having a series of arcuate indentations formed therein, said indentations being spaced from one another so as to form a series of substantially flat areas about the bottom of said flange between said indentations, said areas between said indentations being substantially in the shape of a trapezoid, the topmost point of said indentations extending above the top of said saucer lip when said bottom of said container is placed within said container-receiving area of said saucer, so that the liquid located on the exterior of said container and adhering to said flange is captured by and retained within said indentations when said container is removed from said saucer and tilted for emptying the liquid held in said body of said container, thereby preventing dripping of said liquid from said container.
Claim 11
Independent Claim
197 words
An apparatus for providing dripless consumption of a liquid and comprising: a saucer presenting a concave surface, said concave surface having an upstanding circular lip defining an enclosed container-receiving area thereon in which liquid may collect; and a container having a liquid-receiving body, said body being provided at its bottom with a circular flange adapted to fit within said container-receiving area of said saucer, said circular flange having a series of arcuate indentations formed therein, said indentations being spaced from one another so as to form a series of substantially flat areas about the bottom of said flange between said indentations, said areas between said indentations being substantially in the shape of a trapezoid, the topmost point of said indentations extending above the top of said saucer lip when said bottom of said container is placed within said container-receiving area of said saucer, so that the liquid located on the exterior of said container and adhering to said flange is captured by and retained within said indentations when said container is removed from said saucer and tilted for emptying the liquid held in said body of said container, thereby preventing dripping of said liquid from said container.
Claim 12
Dependent Claim
36 words
The apparatus of claim 9, wherein said areas on the side of said flange between said indentations shed liquid present within said container-receiving area of said saucer when said container is lifted upwardly off said saucer.
Claim 13
Dependent Claim
13 words
The apparatus of claim 9, wherein said indentations are 1/4 inch in width.
Claim 14
Dependent Claim
32 words
The apparatus of claim 9, wherein the outer edges of said substantially flat trapezoidal areas on the bottom of said flange between said indentations have an outer dimension of approximately 1/16 inch.
Claim 15
Independent Claim
179 words
An apparatus for providing dripless consumption of a liquid and comprising: a surface having a container-receiving area in which liquid may collect; and a container having a liquid-receiving body, said body being provided at its bottom with a closed flange adapted to fit within said container-receiving area of said surface, said flange having a series of arcuate indentations formed therein, said indentations being spaced from one another so as to form a series of substantially flat areas about the bottom of said flange between said indentations, said flat areas between said indentations being substantially in the shape of a trapezoid, said indentations being formed so that the topmost point of said indentations extend above the liquid contained within said container-receiving area of said surface when said bottom of said container is placed within said container-receiving area, so that the liquid located on the exterior of said container and adhering to said flange is retained within said indentations when said container is removed from said container-receiving area of said surface and tilted and thereby prevented from dripping from said container.
Claim 16
